Year of construction: 2007, condition: good (used), Chemagen chemagic Magnetic Separation Module I The chemagic Magnetic Separation Module I (chemagic MSM I) isolates nucleic acids automatically within one hour. Viral RNA from 96 nasal swab samples can be isolated simultaneously. The Chemagen MSM-1 is an automated system for high-throughput isolation of nucleic acids (DNA/RNA). It uses a patented magnetic bead technology, in which magnetizable metal rods are immersed in the process solutions to efficiently collect and redisperse the bound particles. Technical Features & Capacity Throughput: The system is modular and can process 12, 24, or 96 samples simultaneously, depending on the rod head used. Sample volume: It offers high flexibility for volumes from 10 µl to 10 ml. Processing time: 96 samples (small volumes): approx. 15–60 min. 24 samples (medium volumes): approx. 35–60 min. 12 samples (large volumes): approx. 45–60 min. Technology: The particles are resuspended by rotating the metal rods at up to 2,000 rpm, enabling high yield and purity without cross-contamination. System Components & Extensions Automation: The MSM-1 can be integrated into standard liquid handling units and often features a 6-axis industrial robot for fully automatic sample tracking. Software: The system is controlled via the chemagic QA software, which is LIMS-compatible. Applications The device is primarily used in research and diagnostics, including: Biobanking and human genetics HLA typing Detection of viruses and bacteria Extraction from various materials such as whole blood, saliva, serum, or plasma System components Actuators: High-precision linear axes for vertical movement and a rotational axis for mixing Electromagnet: Central unit for controlling the magnetic attraction to the metal rods Interfaces: Integrated PC with screen, keyboard, and barcode scanner for sample tracking Software: chemagic QA software (LIMS-compatible, logging, user management) Special features Cross-contamination protection: The use of disposable protective sleeves (tip combs) for the metal rods prevents contact between samples. Automation: Can be combined with the chemagic Dispenser for automated buffer filling or integrated into liquid handling robots (e.g., Hamilton, Tecan). Rod heads: 96 Sampling volume: 10 - 400 μL Number of samples: 1 to 96 samples TFT monitor, keyboard and mouse Year of manufacture: 2007 Gksdsyk Uu Nepfx Afujc Dimensions & Construction Base machine (W/D/H): approx. 600 x 640 x 950 mm.
